โœฆ Synopsis

A new method is proposed for three-dimensional positron emission tomography image reconstruction. The method uses the elementary geometric property of line of response whereby two lines of response, which originate from radioactive isotopes in the same position, lie within a few millimeters distance of each other. The method differs from the filtered back projection method and the iterative reconstruction method. The method is applied to a simulation of portable positron emission tomography.

## Objective: We would like to improve the image reconstructions for both signal-to-noise ratio (snr) and spatial resolution characteristics for the small animal positron emission tomograph yap-pet, built at the department of physics of ferrara university. the three-dimensional (3d) filtered backpr
